Jim--

Good question. Yes, it is a Triumph-Adler unit. Reading from top to bottom
the side of the ECU:

1.  VW/Audi (logos)
2. 025906 021C
3. TAN   (then) Made in Germany
4. TA (logo) (then) Triumph-Adler
5. DIGIJET

(The only possible error in the list above is that at #3 above where I wrote
it says "TAN" it could say "JAN" or something close since the paint of the
lettering has chipped away at the lower part of the "T" or the "J" or what have
you.)

thanks for the info.
Best,
